WINDOW-CLEANING DEVICE.

Specification of Letters Patent.

Application filed February 23, 1911.

Patented Feb. 20, 1912 Serial No. 610,218.

To all whom it may concern:

Be it lmown that I, FREDERICK W. Wool HULL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Window-Cleaning Device, of which the following is a specification.

My invention consists of an improved de vice particularly intended for clearing the windows of the. vestibule of a street car or of a locomotive engineers. cab from snow, rain, sleet or dew without the necessity of opening the window or of using a cloth.

It further consists of improved means for clearing both sides of such window.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating-my invention, I have shown in. the accompanyingdrawings one form thereof which is at resent preferred by me, since the same wi 1 be found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. I

Figure 1 represents an elevation of the outside of a window in a street car vestibule provided withmy improved clearing device. Fig. 2 represents an elevation of the inside of such window. Fig.3 represents a section on the line 02-21: in Fig. 1. Fig. 4 represents a detail face view of the box or casing wherein the device is suspended. Fig. 5 represents a side view of such casing. Fig. 6 represents a sectional detail view "of the frame or" hanger upon which the device is suspended. Fig. 7 represents" a perspective view of a bracketfor one of the wiping bars. Fig. 8 represents a section on the liney-y Fig. 3. Fig. 9 represents a vertical section of a portion of a window and window sash, illustrating another embodiment of my in vention. Fig. 10 represents a horizontal detail section illustrating still another embodiment of the invention. Fig. 11 represents a horizontal section of the form of the device illustrated in Fig. 9.

Similar numerals of 'refer'ence indicate corresponding parts in the figures.

Referring to the drawings, the window frame is indicated by the numeral 1, the window-sash by the numeral 2, and the pane by the numeral 3. Above or in the lintel of the window frame is formed a recess 4, and a rectangular flanged frame or casing 5, is secured in the same by means of screws 6, passing through its flange and into the lintel. The rear of the recess opens through two slots, 7, in the lintel. An H-shaped hanger 8 is pivoted to rock in the flanged casing, screws 9, inserted in the ends of its cross-bar being journaled in cars 10 on the ends of the casing. Shafts 11 are journaled to rock in bearings 12 in the two parallel limbs of the hanger, and have rectangularly bent arms, 13 and 14 secured to their ends by set-screws 15. The lower ends of said arms are pivoted to brackets 16, secured at right-angles to wiping bars 17 and 18, either of which may be brought to bear against a face of the window pane and be moved across the face of the same. One of the arms 14 upon the innerside of the window has a handle, 19, for manipulating it. A catch, 20, is secured upon the window-frame and one of the inner arms 14may engage the same and be held in inoperative position by the same.

In practice, the handle is gripped and the entire device is rocked upon the pivoted hanger to bring whichever of the wiping bars it is desired to use into contact with either face of the windowpane, whereupon a transverse movement of the handle and arms will'sweep the wiping bar across the pane, clearing it of'snow, rain, sleet, ice or mist, or whatever has accumulated upon the sameJ -Bbth sides of the pane may be cleared by rocking the device to bring either wiper in turn into contact with a face of the window pane.

This device is of particular utility for clearing the windows in the vestibule of a street car or in a locomotive cab, although, of course, it may be employed in connection with any window, such as the glass wind shield or front for automobiles or other vehiclesf-and'by its use, the window of such vestibule or cab may be cleared on both sides without the necessity of opening the window or getting on the outside of the same, and without the use of a cloth or other manually handled article or implement.-

By supporting each wiping bar from the two arms pivotally connected to the hanger and bracket at the same distance from each other, the wiping bar has a parallel movement and sweeps or wipes clear across the face of the window pane.

The cross-bar of the l-tshaped hanger is of such diameter that its cylindrical sides will bear against the upper and lower sides of the casing in which it is pivoted, and bearings, 21, are formed upon said sides, so that the entire opening through the window frameis closed, the ends of the cross bar abutting snugly against the ends of the casing.

Tn Fig. 9 of the drawings is illustrated a difierent form of hanger from that illustrated in Figs. 1 to 7. A plate, 22, is secured over the opening or recess 4 in the lintel of the window frame. Brackets 23 and 24, project in opposite directions from the faces of the plate, and L-Shaped links, 25, have the ends of their short arms pivoted to such brackets. A hanger 26, having bearings 12 for the rock-shafts 11, has ears,-27, to which the lower ends of the links are pivotally connected, and the body of said hanger is curved on the arc of a circle and fits to slide in an opening, 28, in the plate.

The arms 13 and 14 and the wiping bars 17 and 18 are of the same construction and have the same parallel movement as those already described. As the hanger is moved inward or outward, swinging upon the links, to clean the outer or the inner face of the window pane, the curve of the hanger admits of the latter moving through the opening in the plate and practically filling the same, thereby excluding draft and rain or snow.

The form illustrated in Fig. 10 of the drawings is intended to be employed with an outer wiping bar, only, and the hanger, 29, has a cross-bar and two bearings 12 for the rock-shafts 11. The hanger has pintles or trunnions, 30 pivoted in ears, 31, in the recess through the lintel of the windowframe. the inner side of which is closed by a plate, 32, having a slot, 33, on opposite side of which are guide-flanges 34, between which the inner end of one of the bearings 12 may be guided. As only one set of parallel arms is used, only the one rock-shaft is carried through the window-frame, and is provided with a handle, 35, for rocking the device and for swinging the arms and wiping bar.
